WeatherExpert® Light Commercial Packaged High Outdoor Air System 48LCH
WeatherExpert® Light Commercial Packaged High Outdoor Air System
48LCH
Gas Heating / Electric Cooling Units with Puron® (R-410A) Refrigerant
6 to 10 Nominal Tons
The WeatherExpert® packaged high outdoor air system is a special configuration of WeatherExpert packaged rooftop unit that can operate with up to 100% outdoor air for ventilation or make-up air in light commercial applications. The WeatherExpert 48LCH includes new options that enable 100% outdoor air operation, including modulating low load protection valve to prevent refrigerant circuit issues at low loads, modulating hot gas reheat for dehumidification with supply air temperature control, 5:1 turndown modulating gas heat for a wide heating operating range, and the exclusive EcoBlue ™ vane axial supply fan a wide airflow range. All units include Carrier SmartVu™ controls for control flexibility, ease of setup and commissioning, and simplified troubleshooting.
